Mac Pro (Late 2013) with macOS High Sierra struggles to work well with Premiere Pro
Let me begin by saying that I have an identical machine at work that works perfectly, with the only difference being that it is still running macOS Sierra.
Machine Specifications:
Mac Pro (Late 2013)
Processor 2.7 GHz 12-Core Intel Xeon E5
Memory 64GB
GPU Dual AMD FirePro D700s
OS macOS High Sierra
After updating my personal machine to High Sierra, I immediately experienced dropped frames while editing Red Raw footage. Keep in mind that I have been editing Red Raw footage on this machine at FULL QUALITY since I purchased it in late 2013, often with multiple layers active simultaneously. Now, after importing a clip, I can barely play the clip back at half quality. I decided to compare this problem to my machine at work, an identical Mac Pro that is still running Sierra, and it plays the clip back at full resolution without any problems. I decided to change my project's settings to use software only, instead of using the GPUs for acceleration, and the playback was identical to my machine at home, the one running High Sierra. This tells me that even though I can select the option to use GPU acceleration (Metal or OpenCL) on my machine at home, Premiere is only actually using software, and I am not benefitting from any GPU acceleration. An application from Red, called REDCINE-X PRO, was recently updated to remedy a similar problem, as it was no longer using GPU acceleration after updating to High Sierra, and now it works perfectly again on my machine at home. Therefore, I know it isn't a hardware issue, so it must be something related to High Sierra. I am looking for the best way to get back to a normal Premiere Pro editing experience, and I thought updates would address this, but so far nothing has helped.
